BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an automatic winder, and more particularly to an automatic winder for winding and unloading coils automatically.

2. The Related Art

Numerous of elongated elements, such as tubes and other kinds of cables, have to be winded to form coils after they are finished. This coil is suitable for package and proper to move or transit. The process is called winding, and the equipments used in the process are winders.

The original winders simply consist of a motor with a plate fixedly mounted on the mandrel of the motor. The plate has a plurality of bars projecting perpendicular to the plate. In practice, the plate is driven by the motor and winds the cables around these bars. When the winding is finished, the coil is drawn off forcibly and completed the process of discharge. The problem of this kind of winders is that the processes of discharge would blemish or deface the cables. What's more, the task of winding would be rather boring and laborious, which makes it an inefficient work.

To conquer the disadvantages mentioned above, winders with unloading apparatuses have been developed. For instance, one such unloading apparatus for automatic winders is described and claimed in CN patent publication NO. 2,228,895, issued on Jun. 12, 1996. Referring to FIGS. 1 and 2, when the winding is completed, two driven cylinders 32 would push a plate 31 forward, and jostle against two rollers 2. Each of the rollers 2 has a screw cap 25 at one end. A front recess 22 and a back recess 23 are set symmetrically at the two sides of the roller 2. A spring 24 holds the roller 2. Under the push of the plate 31, each of the rollers 2 would compress the spring 24 and make its front recess 22 and back recess 24 match a front fixing ring 121 and a back fixing ring 122 respectively. In that case, the two rollers 2 would lean oppositely to make the coil unloading easy and efficient. After unloading, the rollers 2 would resume the forms of erection to get ready for another winding processes.

Although comparing to the initial kinds of winders, the invention has been improved a lot, the instability of the unloading apparatuses blocked its further applications in practice.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 3, the invention of automatic winder comprises a winding apparatus and an unloading apparatus. The winding apparatus comprises a motor 101 assembled to a fixing plate 100 and a movable disc 30 mounted on the end of a rotating shaft 50. The rotating shaft 50 connects the motor 101 and the movable disc 30 crossing the fixing plate 100. The movable disc 30 further comprises a plurality of winding bars 461 for winding wires. This instance of the invention here provides an automatic winder with four winding bars 461. A driven disc 20 is engaged the rotating shaft 50 between the fixing plate 100 and the movable disc 30.

Referring to FIG. 4, the unloading apparatus has a driven device 10 setting between the fixing plate 100 and the driven disc 20 and a plurality of unloading devices 40 fixing between the driven disc 20 and the movable disc 30. The driven device 10 contains at least two cylinders 11 mounted on two sides of the fixing plate 100 as drivers. A driven block 12 is set respectively in the front of a cylinder 11. A driven ring 14 engaged the rotating shaft 50 is set in front of the two abreast-arranged cylinders 11 and mounted on the two driven blocks 12. A first fixing board 151, a second fixing board 152 and two bolster plates 153 are set between the fixing plate 100 and the driven blocks 12 to fix the cylinders 11 and driven blocks 12. Each bolster plate 153 is placed against a cylinder 11 from the inner side respectively. The two bolster plates 153 uphold the second fixing board 152 from one side and clamp the first fixing board 151 from its two ends. The first and second boards 151, 152 engage the rotating shaft 50 through axletrees (not shown). A bolt 13 is intervened into a bolster plate 153 crossing a driven block 12 allowing the corresponding driven block 12 sliding on the bolt 13.

Referring to FIGS. 4 and 5, a cushion device is described here. A cushion ring 16 engages the rotating shaft 50 beside the driven ring 14. Four pillars 161 are set on one side of the driven disc 20 averagely. Correspondingly, four holes are defined on the cushion ring 16, each to engage a pillar 161. Each pillar has a cushion spring 162 engaged to uphold the cushion ring 16. What's more, two guiding poles 163 shorter than the pillar 161 are set symmetrically at the two sides of each pillar 161. The distance between each two guiding poles 163 is a bit wider than the cushion ring 16, allowing the cushion ring 16 sliding perpendicularity to compress the driven disc 20.

As there are four winding bars 461 in the invention, four unloading devices 40 are used here. Here one of the four unloading devices 40 is selected for detailed description.

Please referring to FIGS. 4 and 5 again, an unloading device 40 comprises a driven block 41 having an arched contact surface. The driven block 41 is locked with the pillar 161 and guiding poles 163 and together mounted onto the driven disc 20. Along the line of the driven block 41 and the center of the driven disc 20, a second base 44 and a first base 43 each defining a hole are set separately. A sliding pole 42 is fixed in the holes of the first and second bases 43, 44, and its bottom end connected the arched surface of the driven block 41 through a first wheel 422 assembled at the bottom of the sliding pole 42. A sliding portion 421 having a second wheel 4211 on one end is projected sideward from the middle of the sliding pole 42. Two first elastomers 45 are set at back and front sides of the first and second bases 43, 44. One end of each first elastomer 45 is fastened to the second base 44 and the other end to the sliding pole 42 on the top end. The first base 43 defines a channel 432 in both back and front sides, through which the first elastomers 45 can be mounted on the sliding pole 42. The channels 432 are to allow the sliding pole 42 sliding draw the first elastomers 45. A juncture block 431 is projected sideward form the first base 43.

Referring to FIG. 6, a slot 301 with a certain width is set on the movable disc 30 corresponding to the driven block 41, first and second base 43,44 of the driven disc 20. A less wide pons 46 is set at the inner side of the movable disc 30. A winding bar 461 is locked with the pons 46 and protruded to the other side of the movable disc 30 through the slot 301. The pons 46 is mounted on the bottom of a runner 47. On the other side of the runner 47, a sunken slot 471 is defined running through the runner 47 and a sliding base 48 is locked on the sunken slots 471. An arc 481 defining an apogee on one end and a bottom at the mid-part is defined on the sliding base 48 allowing the second wheel 4211 of the sliding pole 42 moving thereon. On the other end of the sliding base 48, its two sides extend forwards and form a gripper 482 to clamp the juncture block 431 of the first base 43. At the back and front sides of the runner 47 and the second base 44, two second elastomers 49 are fixed separately therebetween. The second elastomers 49 strain the juncture base 431 to the sliding base 48. Meanwhile, the second wheel 4211 connects with the apogee of the arc 481 tightly.

Please refer to FIGS. 4 and 5, when to unload coils, the cylinders 11 of the driven device 10 would be actuated by a signal generated by a control device (not shown) of the automatic winder. The pistons 110 of the cylinders 11 then push the driven blocks 12 moving forward along the bolts 13, meanwhile, the driven ring 14 would be forced moving to meet and push the cushion ring 16. The cushion ring 16 slides forward along the pillars 161 and compresses the cushion springs 162. The cushion springs 162 are compressed and then would push the driven disc 20 moving forward.

The driven block 41 moves with the driven disc 20 and props the sliding pole 42 upwards to draw the free ends of the first elastomers 45 which makes the second wheel 4211 roll from the apogee of the arc 481 towards the bottom and get divorced from the arc 481. Under the pull of the second elastomers 49, the juncture block 431 of the first base 43 then push the sliding base 48 through the gripper 482. Then the end of the pons 46 would be forced moving sideward and be contained into the slot 301 of the movable disc 30. Hence, the winding bar 461 locked to the pons 46 then leans sideward to make the unloading processes easy and efficient. After the coils unloaded, the sliding pole 42 would slid backwards under the force of the first elastomers 45 and the pones 46 be out of the slot 301, which makes the winding bar 461 recover from lean and get ready for the next winding process.

As described above, the invention of automatic winder completes the unloading process by the sliding pole 42 moving upward. The second wheel 4211 of the sliding portion 421 then rolling towards the bottom of the arc 481 and gets divorced form the sliding base 48. Under the pull of the second elastomers 49, the juncture block 431 of the first base 43 presses the front end of the sliding base 48 sidewards and makes the winding bar 461 mounted with the sliding base 48 leans sidewards to help unloading the coils. When the unloading is finished, the winding bar 461 then recover the initial winding state to get ready for next process of winding under the force of the first elastomers 45. Hence, with the help of the unloading apparatus, the invention of automatic winder would make the process of unloading easy and efficient.
